.223 for bear, mountain goat, deer, elk, and moose.

Alright guys, time to stop with the jokes about how effective 223 is, some “data geek with a physics degree” ran the numbers and with 77gr bullets 223 “doesn’t have the sectional density to keep pushing through air more than 200 yards”. That’s right, you heard it here first, after 200 yards your TMKs should be stopping dead! Might as well swap them out for a 22LR!

I had to log in to reddit and leave a comment lol. What an asinine way to look it.
 
Dang that’s pretty funny. .223s being stopped by atmosphere at 200 yards and even when you make a good shot it may “glance off a rib”.

Then some comments about some rounds “lack of authority”. Funny, but unfortunate that grown adults that shoot have such a lack of education on basic physics and how this stuff works.

Dang......I have broken the laws of data geek physics for 3 cartridges so far, that must mean I exist outside of time and space.
 
Another DRT 79 example for the non lead shooters. These were my first two kills with the 223. What a riot to hunt with.

2 whitetail kills during the Wisconsin antlerless season with the 79 terminal shock factory load out of a 16.5” 223 tikka. MV approx 2500 fps. Both shots, reactions, wounds were almost identical but I have the nuance below.

Deer 1: Yearling taken at 7 yards (2480 approx impact velocity) and shot slightly quartering away in crease behind shoulder. Deer ran 35 yards and died. 12 seconds to incapacitation. Bullet stopped in offside humerous with a golf ball sized hole with jacket and powder residue. 9-10” of penetration. Top of heart was blown off and pieces of lung removed when field dressing.

Deer 2: smaller doe taken at 17 yards ( 2456 approx impact velocity). shot slightly quartering away in crease behind shoulder. Deer ran 30 yards and died 7 seconds to incapacitation. Bullet stopped in offside shoulder meat creating a mess and I did not try to fish out the jacket. 9-10” of penetration on this shot as well.

Man. Next time just jump on them and knife them at those ranges!

That dude will never quit. He has a personal hate toward 223 for some reason. Look a little as his comment history and you will find he hasn't hunted in years and some how is an expert on the topic.

Weird. I don't seem to have a problem shooting 75gr ELD-Ms at 600 for Service Rifle. Well, other than the occasional wind shift that I miss and throw an 8 in the mix. It definitely makes it to the target though.
 
Don't know what to tell you, the guy is a physics expert so if he says so it must be true. Nevermind that his numbers are all sorts of fucky.

I wish I had not clicked on that link. Red herring after red herring. Claims the 77TMK are $2.50 per round... SMH.
 
He tried to backpedal it seemed with the quick read I did. I was trying to discern how he came up with the expanded diameter but couldn't reverse engineer it. Maybe I should've stuck with engineering.

ETA: While I generally agree with him on the blood trail part, I've seen wide variability in blood trails. Most of that comes from shot angle (still hunting < stand hunting) and shot placement (higher < lower). I shot a buck this year from the ground high through both lungs with a 20ga slug. I saw the deer lying on the ground before I found hair or blood. I didn't spend too much time looking for blood but the few drops I saw were small which makes me think he'd recently started dripping on the ground from the high shot. The exit was not small (50c piece or so).

Lack of Authority should be taken seriously. I put badges on all my rounds so that they arrive with authority and animals don’t resist. It has affected my BC. But the seriousness of the authority makes up for that.
